A looping beep

My computer crashed and hasn't recovered. When I power it up, it fails to post. A long beep that repeats itself is all that I?m left with. Things I've done to diagnose: Removed RAM Replaced Ram with New Tested Ram (passed) Removed and reseated Video Card Pressed all visible chips Changed power supply Thanx

Re: a looping beep

Try disconnecting power to all your drives. It's possible one of the drives has a short that is bringing down the power supply (most power supplies will shut down if they sense a short, to avoid damaging your computer). If it's not that, it's either a bad video card (reseating obviously won't help if the card's damaged) or a bad motherboard or processor. If you have another machine you can borrow a video card out of, you can test that. Otherwise, you'll have to replace the motherboard and processor. Never replace just one of the two, as one can damage the other and it's not worth frying your new equipment by putting damaged hardware in.

6 beeps

Beep codes are generally grouped together with slight pauses between groups. I would open the cover and make sure that all the connectors are on tight and that the memory hasn't been jarred lose. After rebooting the pc, I would listen carefully to the beeps and find the grouping codes. I am posting the link to the dell support site with the code grouping explanations.

A Comprehensive Guide on Computer Beep Codes. (AWARD BIOS)

When a computer is booted up its BIOS, it performs a power-on self test, also known as POST, to test and verify the computers hardware and to make sure all components are working properly. Here's a comprehensive guide on how to determine which component has failed on a particular beep code and give you an idea on where to start for troubleshooting.

The exact meaning of the beep codes depends on the type and version of BIOS that you have. The three most popular types of BIOS are those made by Award, American Megatrends (AMI) and Phoenix. If you are using a PC made by a company that writes its own BIOS, e.g. DELL, HP, etc, you will have to consult your PC user's manual or the company's web site for assistance.

Beep Codes for Award Bios.


1 long, 2 short = Video adapter error

Troubleshooting: Either video adapter is bad or is not seated properly.

Repeating (endless loop) = Memory error

Troubleshooting: Check for improperly seated or missing memory. Reseat the memory if you can.

1 long, 3 short = No video card or bad video RAM.

Troubleshooting: Reseat or replace the video card.

High frequency beeps while running = Overheated CPU

Troubleshooting: Check the CPU fan for proper operation. Check the case for proper air flow.

Repeating High/Low = CPU failure.Either the CPU is not seated properly or the CPU is damaged. May also be due to excess heat.

Troubleshooting: Check the CPU fan or BIOS settings for proper fan speed.

I will be posting more tips on other versions of BIOS.
Hope this helps.

BIOS Beep Codes
Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem. The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (a faulty video card or no card installed) or if an external ROM module does not properly checksum to zero.
An external ROM module (for example, a video BIOS) can also issue audible errors, usually consisting of one long tone followed by a series of short tones. For more information on the beep codes issued, check the documentation for that external device.
There are several POST routines that issue a POST terminal error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the error to I/O port 80h, attempts to initialize the video and writes the error in the upper left corner of the screen (using both monochrome and color adapters).
If POST completes normally, the BIOS issues one short beep before passing control to the operating system.

I hope this helps.

Frequent, repeated video display crash

Do the re-installation of operating system. Then observe if it will crushes down. If not, then the problem will be the operating system not the hardware. If still crushes down, try replacing the hard disk. Maybe it has a bad sector in it. That why it crushes down always.

Beep sound continus

I went to google and it seems like the beeps can be problems for different problems in the hardware, this is what one message says,  there are lots of computer beeping answers out there: 1 short beep is your BIOS saying "HELLO I'M OK" 

Standard Original IBM POST Error Codes 

1 short beep Normal POST - system is ok 
2 short beeps POST Error - error code shown on screen 
No beep Power supply or system board problem 
Continuous beep Power supply, system board, or keyboard problem 
Repeating short beeps Power supply or system board problem 
1 long, 1 short beep System board problem 
1 long, 2 short beeps Display adapter problem (MDA, CGA) 
1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 
3 long beeps keyboard card 

Each BIOS company has modified these codes over the years.

I have an Asus p4s533-mx motherboard which boots and runs fine (sometimes). But when I perform a warm boot, it often won't pass POST. The beep code is one long and two short. If I power it down and let it...

The response from ASUS tech support - It's a standard Award BIOS, so they're the standard beep codes.

So I wrote the following on page 3-4 of my user guide:

1 long + 2 short = Video adaptor error
1 long + 3 short = No video card or bad video RAM

high freq beeps while running = Overheated cpu

repeating high/low = cpu problem

repeating (endless loop) = memory error

No post, only motherboard light on, green.

Hey there aj1253, It seems you are getting power to the board. are the fans running?Are you using onboard video or video card. Onboard is suggested for test. I would also suggest you reseat your ram. That is removing it and ensuring it seats properly. Beyond that I would ask you provide more info ( ie is this a new build, or did it just stop working, configuration details, model #'s, et....)
